Behaviorism

While i was reading behaviorism, i just kept picturing how humans act nowadays and how things have evolved with the way humans interact with one another and how their behavior has changed in society versus when we were kids and everything felt so free and pure in the world. According to John B. Watson says that psychology was a true science then it should only be based on behavior and not ones irrational thoughts and urges. Yet, isn't that behavior in itself? The urges and tendencies we get every day or when we encounter something its our instinct of behavior how we react to a certain situation? I don't think i fully agree with him on that as our thoughts when we act on them is how our behavior is. You get an attitude thats poor behavior like a kid throwing a temper tantrum that is a kids urge of behavior to act on the situation they are in. I think that behaviorism goes hand in hand with conditioning and a ones ability of learning. It is considered a learning theory to some psychologists. It all comes down to can you shape a behavior at a young at and see where that kid ends up when he is an adult and the world changing around him won't change his behavior? Or you have people who's behavior changes day to day depending the type of day, life events, just anything going on within them and around them. Our behavior comes from learning and from learning it is studied by our way of reading and writing all according to how they do it in research. To me it is just as simple as how one reacts to a certain situation and their behavior can either be deceiving and they act well mannered in a situation or they have a poor attitude. There is a fine line between ones behavior, you just don't know what they have going on that would cause a specific behavior to come from them...
